Abstract:  The Naval Air Development Center is a 840-acre Naval facility located in Bucks County, Pennsylvania. The site lies in a populated suburban area surrounded by private homes, various commercial and industrial activities, and a golf course. On-site areas include various buildings and other complexes connected by paved roads, the runway and ramp area, mowed fields, and a wooded area. In 1993, the Naval facility was renamed Naval Air Warfare Center (NAWC) Aircraft Division Warminster.Historically, wastes containing hazardous substances were generated by NAWC during aircraft manufacturing, maintenance and repair, pest control, fire-fighting training, machine and plating shop operations, spray painting, and various materials research and testing activities in laboratories. The wastes generated have included paints, solvents, sludges from industrial wastewater treatment, and waste oils. From 1940 until 1980, these wastes were disposed in pits, trenches, and landfills located on current NAWC property. In addition, wastes generated by NAWC were burned in a fire training area until 1988.An assessment was performed on the site in 1979 and 1985. The site was placed on the National Priorities List (NPL) in 1989. Since then, investigations into the type and extent of contamination have been conducted.
Remedy:  The remedy for this site is an interim remedy and consists of groundwater extraction, treatment of extracted groundwater at an existing on-base groundwater treatment system, discharge to surface water at the outfall of the subject treatment system, and institutional controls, to continue until the final remedy is implemented.
